The system and method for pretreating turbid seawater utilizes polyelectrolyte dosing, clarification through a clarifier system and centrifugation in a decanter centrifuge followed by microfiltration to treat seawater prior to its injection through a desalination plant. The system for pretreating turbid seawater includes a static mixer for mixing a polyelectrolyte with a stream of turbid seawater to produce a polyelectrolyte-treated seawater mixture. At least one clarifier tank is in fluid communication with the static mixer for receiving the polyelectrolyte-treated seawater mixture and removing a first portion of solids therefrom to produce a clarified seawater mixture. A decanter centrifuge is in fluid communication with the at least one clarifier tank for receiving the clarified seawater mixture and removing a second portion of solids therefrom to produce centrifuged seawater. A microfiltration system is in fluid communication with the decanter centrifuge for receiving the centrifuged seawater to produce the pretreated seawater.

This disclosure describes methods to separate solids from liquids in a production facility. A process separates components in the process stream by applying non-condensable media to create density differences and then using a mechanical device to separate the solids from the liquids based on the density difference. The process produces the liquids and solids, which may be further processed to create valuable animal feed products.

A method for treating aqueous saline streams, specifically saline effluents, by means of membrane distillation with pre-treatments, in order to remove total calcium hardness and permanent calcium hardness and the presence of sulphates in saline effluents, more specifically in residual brines from desalination plants. The system makes it possible to concentrate brines above 37% by weight, i.e. above the saturation level, which makes it possible to reduce the volume of brine considerably, making it suitable for other industrial uses and producing pure water.
