Recovering Waste Water

waste water

One of the ways that a vibratory separator like the Ranger Separator™ can be used is to greatly reduce the Biological Oxygen Demand (BOD) of wastewater that’s generated during the production of decaffeinated tea. To understand the importance if this application of a wastewater recovery screener, you need to first have a basic understanding of why BOD levels need to be contained.

Any time that organic waste — such as grass, leaves, sewage and even tea — is present in water, the microorganisms in the water break down this waste. To do this, they consume oxygen. Their demand for oxygen is stated as the Biological Oxygen Demand. Of course, when there are high levels of organic waste in the water, the microorganisms consume more oxygen, so the BOD levels are high.

The problem with high BOD levels is that the more oxygen the microorganisms consume, the less oxygen is available for aquatic organisms such as fish and water plants. High BOD levels are a threat to the overall aquatic ecosystem.

During the production of decaffeinated tea, tea fines and tea leaves are released into the waste water — yet to contain BOD levels, they need to be filtered out. The Ranger Separator™ uses its vibratory motion to separate out the larger pieces of organic waste — the tea fines and tea leaves — from the water. Assuming that the waste water has then achieved the desired BOD levels according to local and national regulations, the water can subsequently either be pumped away or recycled for use in the decaffeination process again.

Using Wet Screening Equipment to Remove Contaminants From Waste Water

As can be seen from the example above, untreated waste water often contains contaminants that are harmful to the environment. However, it may also contain particles that are considered hazardous for human use. For this reason, the EPA has established Effluent Guidelines, which are regulations that apply to the discharge of waste water to municipal sewage plants as well as to surface waters. The regulations are issued for various industrial categories and compliance is critical.

Screening waste water is usually the first step in the process of removing contaminants from waste water so it can be pumped away or re-used. This process is performed in many industries — including food and beverage, like the example above — as a pretreatment operation. It separates solid-liquid mixtures to remove contaminants from the water.

Industrial Screening Removal

This method of screening is purely based on particle size. It works by feeding a solid-liquid mixture on to a screen that has specifically sized openings on it. Any particle that’s smaller than the opening will pass through, while any particle that’s larger will be caught by the screen. In the waste water treatment, the larger particles are usually removed prior to further treatments that make the waste water safe to be pumped away or alternatively, in the event the water is recycled, safe for consumption.

The Range Separator™ from VibraScreener offers a low-maintenance yet highly effective and productive method of first-line waste water treatment. Contact us to learn more about how it can help your business.

Common Questions About The Screening Industry

question mark

When it comes to industrial and mechanical screening products, it’s understandable that many businesses have questions about the various types of products as well as their specific uses. That’s why we’ve put together this list of FAQs to address common questions and concerns.

What Exactly Is Industrial Screening?

Screening is a technique that’s commonly used to separate materials — either liquids from solid particles (referred to as liquid-solid) or solid particles of different sizes (referred to as solid-solid). At its most basic, the screening technique works by depositing input material onto a screen that has one or more openings in it. When the screener vibrates, everything that’s small enough — whether it’s particles or liquid — passes through the opening. As a result, the materials are separated.

What Kind of Different Industries Use Screening Products?

Screening products are used in a wide range of different industries, including:

  • Food and beverage
  • Pharmaceutical
  • Nutraceutical
  • Cosmetics
  • Chemical
  • Ceramics
  • Metal powder
  • Powder coating
  • Minerals
  • Mining
  • Recycling
  • Agriculture
  • Plastics
  • Aggregate
  • Liquids/slurries

Screening can be used to remove contaminants and impurities from liquids and materials. As an example, screening is commonly used as a pretreatment for wastewater. It can also be used to grade and de-dust products in the food and pharmaceuticals industries. Plus, it can be used to separate out larger items and smaller items — in the gold mining industry, for example. In short, screening can be used for many applications where liquids need to be divided from solids or different-sized solid objects and particles need to be separated.

Can You Help Me Adhere to Industry Regulations?

This is understandably one of the most frequently asked industrial screener questions. Fortunately, the answer is, “Yes.” There are many industries that have regulations, such as Hazard Analysis and Critical Control Points (HACCP) — regulations in the food and beverage industry. Because of this, we manufacture several screeners that are specifically designed for HACCP-compliant use.

If our current screening and sifter machines don’t possess the features you need to adhere to your industry’s regulations, just let us know. We’re always open to discussing how we can help you. For example, we can create a custom machine to your specifications or, of course, the standards set by your industry.

Industrial Screener Problems: How to Spot and Fix Them

Properly caring for and maintaining industrial screens is critical to keeping your material processing line running smoothly. Whether you’re working with aggregates, chemicals, food processing or countless other types of media, particles and materials, industrial screener problems bring productivity to a halt.

A ripped, clogged, damaged or defective industrial screener can result in diminished product quality, additional labor requirements and material waste. By knowing what to check for industrial screener defects, you can spot small issues before they cause more significant problems and keep your business moving in the right direction.

Common Industrial Screener Defects 

Industrial screener problems typically occur when equipment isn’t properly specified, installed and maintained. When you’re having trouble with screens, you may experience poor material handling and off-spec grading results as well as a shorter lifespan for equipment. The most common issues with screeners include:

  • A tear or hole in the mesh or cloth allowing oversized particles to move freely through the system.
  • Screen blinding resulting from an increasing build-up of particles over time causing blocked and overloaded screeners.
  • Material bypass problems occurring because the mesh screen has detached from the frame, or the wire is stretched and penetrated, creating too wide of an opening.

Industrial Screener Troubleshooting

The best way to avoid industrial screener problems is to look out for red flag indicators and regularly inspecting your machines. Check seals and gaskets as well as sliders and balls to ensure they have not been compromised. Also, be on the lookout for holes and tears. Additional solutions to common screener problems include:

  • Selecting a screen with smaller or wider openings
  • Replacing older screens or using backup screens for extra support
  • Using a pre-tensioned screen or an anti-blinding device
  • Slowing down your feed rate and regularly cleaning screens

Cleaning Fine Mesh Screens Without Damaging Equipment

While screen blinding is not uncommon, it is a problem. It can bring material classification to a halt, leading to delays in your entire processing line. That’s why cleaning your mesh screens is essential. You must also ensure your team cleans them without damaging your equipment. To help your company protect its machinery, we’ve compiled a go-to guide that outlines five precautions for fine mesh screening cleaning.

1. Inspect Your Vibrating Screen’s Condition

No matter your screen’s age, it’s critical that your facility inspects it before washing. Look for sags, holes or tears. If you find any, consider replacing or re-screening.

2. Review Your Built-Up Material

If you process materials sensitive to temperature, review their properties. Using hot water, for example, may cause those particles to melt into your screen versus washing off.

3. Choose Your Bottom-Side Screen Cleaning Device

A critical step in cleaning mesh screens is choosing your bottom-side cleaning device, which could include:

  • Sliders
  • Ball trays
  • Sandwich screens

When selecting your cleaning device, consider your material and screen type, as some methods aren’t ideal for certain filters, like ball trays for fine mesh screening.

4. Pick Your Top-Side Screen Cleaning Device

While reviewing your bottom-side screen cleaning devices, also decide on your top-side screening cleaning device, which could include:

  • Rotary brushes
  • Necklace ring dams
  • Wiper ring

Additional methods for cleaning standard and fine mesh vibratory screens include:

  • Vibro ring
  • Water spray
  • Ultrasonic
  • Energizer

If you’re unsure of the best option for cleaning your equipment’s screen, like your vibratory sieve’s mesh screen, contact the manufacturer.

5. Begin Your Screening Cleaning

After you’ve assessed your screen, reviewed its built-up material and chosen devices for cleaning your mesh screen, you can set a time and date for cleaning your screens.
