Why a DAF cell?
A DAF cell is designed to remove suspended solids and oils and greases from a waste. The reduction of Suspended solid and Oil and Greases will also lower your COD.

Can a DAF cell deal with mixed waste streams?
Yes. A DAF cell will deal with mixed waste streams. The DAF cell comes with a flocculant dosing system to help separate the contamination from the water phase of the waste.
The minute air bubbles created by the patented aeration device in the WMEC DAF cell carry the separated waste to the surface of the water.

My flow is irregular and I thought DAF cells need a regular flow
Yes DAF cells do need a regular flow and loose efficiency by stopping and starting.
The WMEC DAF cell’s aeration device allows the system to stop and start with built in delays to ensure no loss of efficiency.
A regular flow is provided by a storage tank that is part of the DAF package.

How much reduction in Suspended Solids can I expect from a DAF cell?
A DAF cell will remove up to and in excess of 75% of your Suspended Solids. This removal will also decrease your COD levels by a similar amount.
The suspended solid will be removed from the DAF cell by an integral sweeper arm.

I do not have enough room for a Biological plant.
When we think of a biological plant we often think of a municipal plant that covers a large area.
The BAFF’s patented treatment system increases the efficiency of removal of organic contaminates many times more than a standard municipal activated sludge plant. This efficiency can be as high as 6 times greater, thus the plant can have a far smaller foot print.

How big is the plant?
A recent plant to treat 2 to 3,000 litres per hour of effluent 24/7 covered the area of three 40-foot containers. This plant contained a pre-tank, treatment tank, settlement tank and control room.
A complete plant to treat 5,000 litres per day covered an area of a 40-foot container.

What kind of waste will a Biological plant treat?
Biological plants treat the soluble organic waste in your waste stream. The Biological plant has system to remove the insolvable suspended solids prior to the biological treatment phase.
The Aerobic process treats waste with average BOD loadings up to 6000 mg/l and can reduced this to low 20 mg/l.

Why a BAFF type biological plant?
Biological activated fixed film plants offer increased efficiency for size over activated sludge plants.
The multiple three-box treatment system of the BAFF design allows the system to deal with some wastes that in normal circumstances would never be treated by a Biological plant. This is because the EnviroBAFF system is designed for industrial waste with higher COD BOD ratios than possible in other types of plant.

Can I treat my waste that is a mixture of organic and inorganic products?
Yes, the flocculation process can use a variety of flocculants to break both the organic and inorganic contaminates from the waste stream.
The process is designed to treat higher levels of contamination than one would normally give to a DAF cell.

Can I treat waste with mixed inorganic contaminates?
Yes. The flocculation system is a robust treatment system that can deal with mixed waste streams. In some cases tertiary treatment will be required to meet Water Authority drain discharge limits.
WMEC plants are often dealing with inorganic materials suspended in organic agents with inorganic levels of over 1000 mg/l needing to be reduced to less than 2 mg/l.

Can I recycle the water from this process?
Yes, the process gives you a water that is clean enough for wash down usage and if required clean enough for process use.

Does the WMEC plant come as a complete package?
Yes, we sell complete plants that take waste from your out line, treat and then dispose or store for reuse.
We also manufacture complete units with bunds for export, which have been installed in over 20 countries worldwide.

The pH of my waste varies from minute to minute during the day.
The WMEC batch treatment pH plant can store mix and treat both high and low volumes of waste to correct the pH both increasing or decreasing the pH as required.

I do not wish to restrict my CIP wash out process because of pH control.
Multiple pH treatment systems including both inline and batch correction can deal with very high hourly discharge requirements up to 40,000 litres per hour, or treat and store to balance outflow to meet sewer discharge flow limits.

My waste is very concentrated with either acid or alkali.
Relatively small batch treatment units that will treat the waste carefully to ensure that secondary reaction such as temperature rise can be controlled.
In some sites that have both Acid and Alkali waste we can take either waste and using your own opposite product reduce or increase the pH as required.

I need to treat relatively high flows regularly.
WMEC Inline plants with capacities up to 3000 litres per minute have been used to correct high flows from land remediation sites.

What does the SENTINEL Pesticide waste treatment system do?
The system is designed to treat dilute pesticide and dilute pesticide washings.
The SENTINEL process cleans the water so that the pesticide contamination is reduced by over 99.9% to levels where the wastewater can be safely returned to the environment or reused.

Can the SENTINEL treat wastewater with more than one type of Pesticide contamination?
Yes. The SENTINEL treatment system has been used for treating wide mixture’s of pesticides in wastewater throughout the World reducing the pesticides concentration to below the legal disposal requirements.
The SENTINEL plant is in operation in over 35 countries Worldwide and has been independently tested by over 15 Universities and Governmental authorities.
In two Independent tests carried out in the last 12 months the SENTINEL plant and process gave outstanding results with over 99.99% reduction of contamination in both cases.

How do I treat the wastewater from one type of Pesticide to another?
All SENTINEL plants use a standard three-strand process of chemical flocculation, settlement and carbon absorption.
For pesticide washings from spraying or similar processes the treatment system uses a standard set of chemicals weighed to suit the size of SENTINEL plant you have. This amount is standard throughout the world whatever the Pesticide used.

Can the SENTINEL treat wastewater from Pesticide manufacturing, blending and packaging?
Yes. The SENTINEL plant is operating in over 100 Pesticide manufacturing, blending, packaging and testing facilities and plants worldwide.
The SENTINEL plant is operated by many of the worlds major manufacturers as well as many local mixing and blending companies.
The SENTINEL plant is not able to treat concentrated Pesticide waste.

What is a VACUDEST plant?
The VACUDEST plant is a fully automatic vacuum distillation system for the treatment of concentrated wastes particularly from metal plating.
The system utilises a vacuum generation system to distil the waste to give a very clean water part and a concentrated sludge for disposal.

Why use a VACUDEST?
The VACUDEST is very suitable for treating concentrated waste streams particularly from the metal plating and pre treatment industries.
Water Authorities are tending to decrease the levels at which inorganic contaminates may be disposed to sewer. The disposal of the concentrated waste from these processes is also becoming very expensive.
The VACUDEST offers an economic solution for the reduction of these costs and contamination levels.

To distil waste must use a lot of energy.
Both high and low vacuum distillation is the least expensive option for this process and on average uses 80 watt per litre treated.

The VACUDEST must be a very large plant.
No, a VACUDEST to treat 6000 litres per week is smaller than a modern two-door refrigerator.
