Wastewater Purification

Coind has designed a chemical-physical system capable of purifying ship bilge water producing a discharge compatible with current regulations for discharge at sea. Bilge water consists of a mixture of hydrocarbons with brackish water in various proportions, the quantity and quality of which can vary from a minimum of 10% up to 50% of the liquids taken. Treatment of the effluent consists of separating the oil from the water directly inside the storage tanks. In this way, the oil can be transferred to an equipped center that will transform it into a recovery fuel, and the water can be purified in the chemical-physical plant built by Coind.

Removal of organic molecules by passing water or air over a bed of granular activated carbon. The operation can be manual or automated with pneumatic valves.

Separation of suspended substances or colloidal systems from water flows, upstream or downstream of a production process.

Dosage of oxidants for water sterilization.

Separation of coarse molecules that allow for the reduction of machinery space and exponentially increase water quality.

Removal of iron molecules present in the water stream. It is done by oxidative systems or with specific ion-exchange resins.

Reducing the bacterial load of liquid in transit. From chemical oxidant dosing to new UV/Ozone technologies.

Treatment of animal manure by electrolysis and electrocoagulation to obtain soil suitable for the parameters required for use in agriculture.

Separation of materials of different sizes present in the water flow. Filters work by gravity, as in the case of channel grates or the auger filter.

Production of demineralized water through semipermeable membranes on pressurization systems. When installed downstream of purification systems, it allows wastewater recovery, with the possibility of using the flow again in productions.

Temperature regulation of water flows. It is applied with heat exchangers or specific unit heaters.

Use of specific facilities to recover water flows directly into productions.

Separation of sludge by settling systems and subsequent thickening before dewatering through a filter press in a sludge warehouse.

High-level filtration by displacement of fluid over membranes. It is used for primary water purification or to separate molecules.
