Reverse osmosis is a technology developed in the 1960s, in which saline or impure water is forced through a semipermeable membrane that retains dissolved salts and impurities, resulting in purified water.

The membrane separation process removes more than 99% of total dissolved solids, organic matter, bacteria, and other particulates.

The permeate flow rate is adjusted based on operational parameters such as temperature, osmotic pressure, conductivity, and recovery.

Changes in operational parameters, such as a decrease in permeate flow, an increase in osmotic pressure, or a rise in conductivity, indicate variations in operating conditions and may be caused by fouling, scaling, or microbiological growth.

The feed water of a reverse osmosis system must be dechlorinated to prevent membrane oxidation. The rate of chlorine attack depends on the characteristics of the feed water. In an alkaline pH, membrane oxidation due to chlorine exposure occurs faster than in a neutral or acidic pH. Chlorine damage also accelerates with higher temperatures and increased concentrations of heavy metals, such as iron.

Centrifugal decanters operate in phase separation, enabling the recovery of raw materials for industries such as food processing, slaughterhouses, dairies and beverages, animal feed and by-products, chemicals, fossil fuels, and more.

The equipment can be used both in the production process and post-processing, whether for water clarification, sediment removal, compliance with environmental regulations for effluent treatment, or proper disposal of these effluents into receiving bodies.

Gratt steam dryers are designed for drying sanitary and industrial waste, as well as various animal and plant by-products. After dehydration, the material can be used for thermal energy generation, organic fertilizers, or animal feed.

The system includes a reception hopper, screw conveyors for feeding and extraction, an exhaust system for gas removal, a cyclone for fine separation, and an absorption tower for gas washing. The layout is customized according to the client's plant.

The dryer features a circular structure with one or two rotating shafts equipped with heating tubes. The indirect steam heating system (6 to 10 bar) ensures efficient drying without direct contact between the product and the heat transfer fluid. A scraping system prevents material buildup, optimizing performance and longevity.

Dissolved Air Flotation (DAF) is a process used to remove suspended solids, oils, and grease from wastewater. It works by injecting air into the effluent through microbubble pumps. The air bubbles attach to solid particles, making them rise to the surface, where a scraper removes the floating sludge. To enhance the efficiency of the process, coagulants and polymers are added to improve floc formation. DAF can be used in primary treatment to separate solids from liquids, replacing sedimentation systems. In tertiary treatment, it helps remove nutrients such as nitrogen and phosphorus, improving effluent quality and ensuring proper water clarification.
