Industrial Wastewater Treatment Systems from Baldwin Industrial Systems

• Step 1: The acidic component becomes active, reducing the pH and breaking oily emulsions
• Step 2: Cationic polymers attract the oil and some of the sparingly soluble negatively charged species such as phosphatesStep 3: The basic component becomes active, raising the pH high enough for removal of metals, which form insoluble hydroxide precipitates
• Step 3: The basic component becomes active, raising the pH high enough for removal of metals, which form insoluble hydroxide precipitates
• Step 4: Heavy metals remaining in solution exchange with the sodium on the clay and bond to the clay by electrostatic force
• Step 5: The reacted mass becomes permanently encapsulated by the clay particles leaving clear water, and a non-leachable sludge

Chemical Treatment Benefits

• Safe and Simple: Chemical handling and storage facilities are minimised; only one non-toxic chemical is required as opposed to three or more using conventional wastewater treatment.
• Sludge Disposal: The micro-encapsulation process, in most cases, creates a sludge that is non-leachable and can be disposed of directly to non-hazardous landfill. Sludge volumes are minimised as the clay base retains no chemically held water.

• Small moulded “Busta” manual units are for treating 300-500 litres per day
• Semi-Automatic units require minimal operator time and are available in painted mild steel construction and ideal for treating 750-1000 litres per hour
• Fully automatic units are PLC controlled and of stainless steel construction. Treatment rates range from 1000 litres per hour up to 10,000 litres per hour and can continually treat without operator attention 24 hours a day
