COSMETICS APPLICATION EXAMPLE PROJECT

WORK SCOPE

PROJECT DATA

Wastewater characteristics: In this sector, waste waters usually result from reactors and other process equipment washing. These waste waters contain several contaminants increasing load values above limits approved by regulation authorities for water discharge, such as tensoactives, FATs, suspended solids, COD and BOD.

Providing a system to treat this wastewater for discharge safely to a sewage system and saving money by reducing sewage discharge fees.

Inlet COD - 11000 mg O2/L Inlet BOD - 1500 mg O2/L SS - 4000 mgO2/L Flowrate - up to 3000 L/h

Wastewater treatment process with the following steps: buffer tank, electrocoagulation cell, Flocculation/ DAF treatment process (VAMEF) and sludge dewatering system. The buff er tank is important to minimize effluent variability (both composition and hydraulic) to the downstream wastewater treatment process (Electrocoagulation). Water level in this tank is controlled by the VAMEF control panel. Electrocoagulation uses an electric current to generate beneficial ions (Fe/Al) into solution while simultaneously releasing gas via electrolysis and breaking long molecular chaines through oxidation processes. The beneficial ions and their byproducts with both dissolved and suspended contaminants increase their precipitation from solution and subsequent removal from treated water. This process is important to remove tensioactives and BOD removal.

Flocculation and separation process will be performed through a DAF unit (VAMEF). This compact dissolved air flotation unit, includes stirred reactor, top sludge scraper, electronic dosing pumps, dosing tanks, pH controller equipped with pH probe and associated dosing pump for neutralizing agent. Furthermore, the system is controlled with an electric board with touch screen.This system allows a very effective depuration, reducing COD, BOD, tensioactives, Fats and SS, in accordance to regulations and usual requirements. The sludge will be discharge by a pneumatic pump to a dewatering system. The dewatering system can be either a filter press or filter bag units, depending on the amount of sludge generated. Finally water will be suited for discharge in receiving pit to connect to public sewer complying with the discharge regulations.

Please find the description in the previous example.

The waste water treatment in this case has the following order: buffer tank, chemical coagulation / flocculation treatment process (VAMEC), sludge dewatering system (PSS) and treated water storage tank. The buffer tank is important to minimize influent variability (both composition and hydraulic) to the subsequent waste water treatment process (VAMEC unit).The level of this tank is controlled by the VAMEC control panel. Chemical treatment will be performed through a settlement compact unit (VAMEC) with a continuous

The VAMEC units include the chemicals feeding pumps (coagulant, flocculant and neutralizing agent), reactor for mixing, pH controller and settler device to separate the resulting sludge. Furthermore, the system is controlled with an electric board (GSM optional). This system allows a very efficient depuration, reducing COD and SS, in accordance to reuse the treated water for several industrial situations such as washing equipments and spray painting booths. The treated water is pumped to a storage tank. The sludge is discharged by a pneumatic pump to a dewatering system. This system is a low pressure filter
