The WWL flotation units are robustly built and characterised by large "free surface" areas. For wastewater containing large solids contents, the design provides sufficient retention time for separation and pre-dewatering of the skimming.

The CPL and PWL flotation units are designed to treat wastewater with a high COD contents. Furthermore, suspended solids, fats, oil, grease and other floating materials will be removed. The CPL and PWL units are designed to achieve a complete laminar flow through the unit, this way optimal separation of the particles takes place.

The PCS and CPS cross-flow separators are designed to separate settling parts like fibers, starch and sand from the wastewater.. Depending on the type of wastewater a PCS settler (executed with one or more sludge cones for the bottom sludge) or a CPS settler (executed with an auger sludge thickener for the bottom sludge) is applied. Each separator is custom built. Depending on your wastewater stream, the number of plate packs, the plate distance, the distance between the plates and the plate inclination are calculated. The PCS and CPS units are designed to treat wastewater flows from 1 up to 660 m3/hour per unit.

The flume system is developed for instantly removal of all vegetable cuttings and waste of the production departments concerned in the fresh cut industry. This ingenious and robust transport system is installed in the factory floor underneath the production lines. The flumes transport the cuttings from the Low Care and the High Care area to a central waste discharge area and discharge them into a container within a couple of minutes.

We have developed a range of efficient separators to remove fast settling materials, like sand, from water. Based on the difference in specific gravity between the water and the settling materials, predictable and maximum separation efficiencies are achieved. A shaftless conveyor, installed at an ideal angle, transports the separated materials to the discharge point above water level. During transport, water flows back into the main compartment resulting in a relatively dry product. Depending the required quality, the purified water can be reused. The separator is standard manufactured from AISI 304.

The water passes through a filtering grid made of bars, the solid parts are collected and conveyed by special cleaning combs to the top of the screen.The particular shaping of the bars allows expulsion of the solids and accurate cleaning of the combs. The rake screen solves the problem of separating solids from liquids in a reinforced concrete channel or in a dedicated stainless steel housing.

Removes the bulk of the coarse solids from the water quickly. Preventing their contents from dissolving, lowering overall sludge production and reducing the operational costs.

Curved screens are applied for separating solids from process and wastewater. The curved screens are robustly built and require a minimum of maintenance and attention. The raw wastewater is pumped over a curved, wedge wire, screen plate where separated particles slide down, due to gravity and the screened water leaves the screen via the outlet. For very heavy polluted wastewater, a vibrating screen plate can be installed in order to guarantee clog-free operation.
