Technological strategies for preserving the environment

Concerned about the rapid growth of cities and the requirements for appropriate measures and technologies for the maintenance and performance of their treatment plants, Ecosan, a leader in equipment for primary and secondary wastewater treatment and Industry, through its division of O&G – Energy, offers more appropriate technological strategies for the preservation of the environment.

“We offer more suitable technologies and we seek the highest final quality index. We pay attention to the best balance between capex x opex and the lower energy consumption, with reduced environmental liabilities in reduced spaces “, says André Telles, CEO of Ecosan.

CAPEX is the acronym for the English expression “CAPitalEXpenditure” (in Portuguese, capital expenditures or investment in capital goods) that indicates the amount of money spent in the purchase of capital goods of a particular company. OPEX is the acronym for the English expression “operationalexpenditure” (in Portuguese, operating expenses) that refers to the cost associated with the maintenance of equipment, expendable consumables and other operating expenses. For example, purchase a maintenance contract or outsourcing (outsourcing of the operation).

Here are some of the features highlighted by Ecosan:

ZLD – Zero Liquid Discharge

More and more legislation and industry require minimal discharges of liquid with a solid product that can be sold or dumped in a landfill. This option implies concepts, for example, total evaporation, crystallization, mixed or combined with membranes. This is the state of the art of treatment.

Systems for Water produced

The management of oil produced water (AP) constitutes a huge challenge for oil companies. The alternatives usually adopted for their destination are disposal, injection and reuse. In all cases it is necessary to treat the AP in order to avoid damage to the environment and to the production facilities or in order to allow its reuse without causing damage to the processes in which the AP will be used.

Membrane separation processes have been shown to be able to treat effluents that have high levels of emulsion oil and particles with medium and small sizes, thus competing with more complex treatment technologies, such as Flotation.

Oily water Treatment (OIW, Wio)

In the face of the increasingly stringent demands of environmental regulators, the environment of oily water generated in various industrial activities is currently one of the biggest challenges to the perfect environmental adequacy of industries and Service providers who operate in the most varied branches of activity.

The services of the petroleum industry such as drilling, production, transportation, refining and distribution generate effluents classified by their dangerousness that should receive specific treatments for removal of their contaminants. Refineries usually use primary and secondary wastewater treatment. The primary treatment comprises the segregation of water, oil and solids in two stages. In the first stage, a water-oil separator (SAO) is used, allowing the oil to be free in the supernatant and can be removed.

Advanced oxidative processes

The treatment of toxic industrial effluents is a topic of extreme interest due to the great impact caused by an inadequate process. Advanced oxidative processes (POA) are technologies developed in recent years and are based on physicochemical processes capable of profoundly altering the chemical structures of contaminants (organic and inorganic compounds), as well as in Inactivation of microorganisms.

Local Power generation arrays

The objective of this process is to quantify the potential of generating electricity from methane gas from sanitation waste, emphasizing garbage and sewage. The effort towards the use of effluent energy technologies would represent a stimulus to the implantation of sewage treatment systems, especially in the peripheral areas of the cities, with extremely positive reflections in terms Social, environmental and public health.

The use of Rankinie’s Cycloloss aims to take advantage of the residual heat to assist the evaporation processes in energy production. In this way it provides a production of CO2-free energy from residual heat, increased energy efficiency, resource conservation and independence through the use of self-generated energy.

Aerated-anoxic Biological treatment

The term “anoxic treatment” is presented as a technology designed for maximum degradation of organic matter in its effluent where the most appropriate technological strategy seeks the highest final quality index, to the lowest energy consumption, with reduction of Environmental liabilities in reduced spaces. It incorporates a special control of the biological reaction within your system.

It is extremely versatile to monitor biological reactions within sewage systems and wastewater treatment plants, as well as as a source of clear indication to operators on biological activity in the process. Incorporated into the process are the high-yield decanters.
