Solutions for water, sewage and industrial effluent treatment

Fast focuses on the sanitation sector with constant investments in Research and Development and strong partnerships, such as the Uruguayan specialist: Seinco. This enables it to offer truly effective solutions, presenting high efficiencies in water, sewage and effluent treatment with significant environmental and operational gains. Among Fast's technologies, the compact systems for treating industrial and municipal effluents (ETEs) and water treatment (ETAs) stand out. The result is high-quality treated water and solid waste with low moisture content.

They are compact systems, manufactured with high quality raw materials, which guarantee a long life cycle, low energy and chemical consumption.

Advantages:

Development of complete plants, from civil design to the operation of ETEs and ETAs.
Lower investment value compared to conventional systems.
Compact systems. With a smaller area being occupied, the required structure is reduced, as are construction times and costs.
Prefabricated in long-lasting construction materials (usually stainless steel or polypropylene) and does not depend on climatic conditions for construction;
Operation with a high level of automation.
Possibility of applying the treatment in stages. Completely assembled or pre-assembled units, quick to install and small-scale civil works.
Lower operating cost compared to conventional systems.
Modular and easily expandable system.
Reduced consumption of chemical products. There are cases of reduction of between 20% and 40% in the consumption of coagulants and flocculants, in relation to conventional processes.
Lower flocculation requirements, facilitating the process and requiring less operator attention.
Each module starts and stops extremely quickly. There is no maturation period, typical of conventional sedimentation.
Continuous, denser sludge discharge is extracted from the surface. This prevents clogging and the need for cleaning. The sludge blanket is visible, stable and has an automatic scraper.
High tolerance to hydraulic and/or organic overloads.
Water savings: the flotation process reduces water loss through discarded sludge and filter washing water.
Water reuse: the Fast flotation system allows the installation of complementary equipment that enables the indirect or direct reuse of water.
It eliminates the need for grease traps and septic tanks for collection, reducing infrastructure costs for treating sewage or industrial effluent.
Sludge dehydration: sludge dehydration, using a centrifugal decanter or tridecanter, produces low-moisture solid residue and high-purity fat, with a range of possible applications or responsible disposal.
National 100% equipment.
High level of automation. The PLC can manage the following parameters: feed pump, chemical tank level, automatic chemical addition process, pH monitoring system, among others.

Industry

ETE – Industrial effluent treatment plant

Fast offers solutions from the preliminary treatment of raw effluent to the reuse of treated water for small, medium and large companies.

Fast's effluent treatment systems are highly efficient and are supplied in pre-industrialized units with treatment capacity starting at 5 m³/h. These include physical-chemical, biological or both combined processes. The system meets all the parameters required by environmental legislation, such as: COD (chemical oxygen demand), BOD (biological oxygen demand), P – phosphorus, NKT – nitrogen and toxicity.

The waste generated in the process, with very low moisture content, can have several uses, such as composting, animal by-products, fuel, etc. In some types of effluents, the treatment plant can become totally sustainable and even generate profits for your company with the recovery of solids and fat or even the use of biomass generated in the process for boilers, due to its calorific value.

Industrial WTPs – Water treatment plant and reuse water

To make water from rivers or underground wells drinkable, available to return to the production process, returned to nature or for consumption, in accordance with current Brazilian regulations, it is necessary to install a water treatment plant, popularly known as ETA.
Fast WTPs are characterized by being compact, easy to operate and low consumption of chemical products.

Raw water, whether surface or groundwater, can be treated using the following processes: coagulation, flocculation, clarification, filtration and disinfection. Chemicals such as inorganic or organic salts are added to coagulation and flocculation. Clarification, the process by which most contaminants are separated from clean water, can be performed using two separation methods: flotation and decantation, which are very compact and highly efficient in removing suspended solids and precipitates. They significantly reduce other parameters (color, odor, taste, among others). After clarification, the treated water is sent to the filtration process for polishing and disinfection, which will ensure the water meets potability standards.

Municipal Sanitation

ETE – Municipal sewage treatment plant

Fast technologies for basic sanitation are widespread in several Brazilian states and exported to other countries, benefiting millions of people. In addition to preventing damage to the environment, treated sewage reduces the incidence of diseases in the population and improves quality of life. It also generates significant impacts on the economy, since for every real invested in sanitation, approximately 4 reais are saved in healthcare.

Fast has extensive experience in implementing increasingly efficient and sustainable solutions for municipal sewage treatment, having participated in important projects recognized for their innovation and efficiency. Developed in full environmental compliance, Fast develops everything from the civil project to the assisted operation. Modular systems, in the case of sewage treatment plants, allow for decentralized installation, which allows for subdivision by neighborhoods, villages and condominiums. It eliminates the need for grease traps and septic tanks for collection, reducing the costs of infrastructure for sewage treatment.

ETA – Water treatment plant

To make water from rivers or underground wells drinkable and available for consumption in accordance with current regulations, it is necessary to install water treatment plants, popularly known as ETAs. Fast Water Treatment Plants They are characterized by being compact, easy to operate and having low chemical consumption.

The treatment of raw water, whether surface or underground, occurs through the following processes: coagulation, flocculation, clarification, filtration and disinfection. coagulation and flocculation occur through the addition of specific chemical products, which can be inorganic or organic salts. clarification, a process where most of the contaminants are separated from the clean water, can be carried out by two separation methods: flotation and decantation. Both processes are quite compact and highly efficient in removing suspended solids and precipitates and present a high reduction in other parameters (color, odor, taste, among others). After clarification, the treated water is sent to the filtration, for polishing, and for disinfection, which will guarantee the standards of potability. Discover some of Fast's cases:
