TREATMENT TECHNIQUES

The special qualities that set our systems apart are their optimal versatility, ease of use, ease of installation and moving, and the ability to vary their operating cycles to suit individual needs, without having to design a new machine.

The G.O.S.T. system totally eliminates all the needs for under- or above-ground tanks, considerably reducing installation and operating costs. Since there is no need for primary tanks, the loading pump is installed directly on the bottom of the collection pit. As all the solid materials gradually arrive, up to 1.5 cm, they are bypassed into the settling tank.

The G.O.S.T. system visually has a compact cubic or rectangular shape, with smooth sides hinged to the structure for easy, constant control of its status. The cabinet containing the treatment system holds: on the left, the dosing pumps with their reagent containers; in the back, the gate valves for draining the sludge and the bottom of the tanks; on the right, the electrical panel for the controls and commands of the system functions and the electrical power inlet.

TECHNICAL CHARACTERISTICS

The G.O.S.T. treatment system uses a modular system that may be described as follows:

• as it is modular, the technical design can handle any situation, present or future; as pollution conditions change, the system can be adapted to any environmental changes that may occur over time;

• its compact structure eliminates the need for fixed settlement tanks for its operation, so the G.O.S.T. treatment system can be removed from its original position and used at other sites (this can be very useful for individuals, such as craftsmen, who might move their business to a new location, for dumps that are closed because they are filled to capacity and the treatment system is moved to a new dump, for needs of local and public authorities and other entities);

• the modular design renders the treatment system functional for any need; each chemical-physical treatment module can work using five reagents.

HORIZONTAL SYSTEM

We use the term “horizontal” to refer to the quantitative treatment potential of a system; i.e. where the hourly treatment need exceeds 10,000 liters/h, it is possible to add modules that double, triple, and so forth, the amount of water, without a proportional cost increase, since the added modules are, in effect, only the expansion of the capacity for containing the water to be treated.

VERTICAL SYSTEM

We use the term “vertical” to refer a treatment system in which the effluent to be treated is drawn from the pit and sent into the upper clarification tank, from which all the treatment processes take place naturally, i.e. by spillover, until the process is concluded with filtration.

The absolute construction simplicity also means functional adaptability, as our chemical-physical system can adapt to considerable variations in both pollutant reduction and the reagents used for its treatment processes. The combined application of the chemical-physical and biological purifiers is another element that makes G.O.S.T. treatment systems highly practical.

This integrated system can be applied to any wastewater treatment situation. The chemical-physical treatment system can reduce all inorganic polluting agents (e.g., oils and metals), which are usually the main causes of the malfunctioning of large and small biological treatment systems. This results in a preselection process, reducing oily, mineral, metal and other pollutants, followed by a complete breakdown of the organic substances by our biological systems.

CONTROL PANEL

Special attention was given to our control panel and its components. All offer a high degree of protection in compliance with applicable laws. The system has low electrical power consumption. All phases, such as loading pump control, treatment control, and booster pump control, are operated either automatically or manually.

Upstream of all electrical power is a differential switch with a 0.030 mmA sensitivity.

Each control has a thermal-magnetic circuit breaker for overload and short circuit protection.

Each motor has its own motor protector with shutdown alarm light. There is a light for the regular operation of the treatment cycle, and a shutdown light.

OPERATION SYSTEM

As the water gradually arrives in the pit where the process effluents flow, the special submersible pump equipped with floats transfers the effluent containing the polluted parts into the settling tank. The effluent then goes into the degreasing tank, where the oily and greasy component is separated; from there it goes into the first mixing tank, and then into the second and third, until it arrives at the settling-clarification tank.

The effluent then overflows and is collected in a tank; by means of a pump it is then sent into the sewer pit. The polluting substances held back in the process are transferred into a thickener, filtration bags, or a percolation bed. This all takes place automatically through the principle of communicating vessels and by overflow. The entire stirring and mixing function is performed with pneumatic stirrers by air insufflation.

COMPUTERIZED SYSTEM

The computerized system uses the same structure and process, but is set apart by the high technology applied to the process itself, which can be described as follows: sludge drainage control with automatic opening and closing of the gate valves set by the system operational parameters, control of chemical reagent inlet, end-of-product alarm, no-air alarm, control and drainage of treated water, a meter to measure the water actually coming out of the system, and an alarm box for sending alarm messages to fixed telephone line or mobile phones.

ADVANTAGES OF OUR CHEMICAL-PHYSICAL SYSTEM

·         Simple, rapid installation:

·         The only construction work required is the preparation of a base on which to set the unit. The electrical power required is normal mains power (220 V).

·         Energy savings:

·         Our chemical-physical system uses a negligible amount of energy, necessary for the functioning of small pumps, some for the dosing of the reagents and others for moving the effluents.

·         Complete wastewater treatment:

·         Our system serves numerous functions, such as a storage tank, the separation of solids, degreasing with a storage tank for the recovery of oil, tanks for the addition and mixing of chemical reagents, settling, clarification, quartz sand filtration, and activated carbon refining.

·         Total adaptation to different polluting loads:

·         The pH-meter and dosing pumps with their programmable flow rate let our system adapt to any polluting load present in the effluents to be treated.

·         Optional components:

·         Our system can be computerized and controlled by the maintenance department by phone.
