Effluent Separation Systems

Sediment Traps • Storm Water Effluent Management • Gravity Effluent Separation

When it comes to Effluent Separation Systems, Ecotech Africa employs various Effluent Separations methods as stand-alone systems or in conjunction with each other, depending on the specific requirements and effluent type.

Critical Factors

To Consider Before Designing a Separation System
icon

Retention, Catchment and Maximum Flow

Hydrocarbons needs minimum 30min settling time to separate significantly from effluent, sufficient settling time must be catered for in the sumps to accommodate at least 30 min retention. The retention is based on the max flow generated from the Catchment Area; maximum flow is determined by the maximum rain that an area may generate in a 1 in 50 Year flood. Although daily flows are also taken into consideration, maximum flow generated from the catchment area will be the main design criteria.

The use of Degreasers or other Emulsification Agents

Traditional degreasers emulsify oil and water thus emulsified oil, grease and fat are no longer separated from the effluent. Retention times of 72 hours are necessary to separate 89% of oils from water using these historical degreasers. In this scenario standard Effluent Management Systems only separate a maximum of 20% of the emulsified oils. The balance is discharged into the sewer or storm water as effluent. De-emulsification will only occur downstream with disastrous result for downstream users. The use of an Environmental degreaser with a retention time of less than 10 minutes, resulting in no emulsification in the separation system. The efficiency of separation system will increase thus increasing the recovery rate of hydrocarbons. The above stated requirements are the basis of providing a sustainable Effluent Management System.

Point of source Pollution Control

Point of source pollution control in one of the key issues in the DWAF best practice guideline. This entails the eradication and prevention of the pollutants where they are respectively generated. A good example of this principal is the implementation of a separation system at a wash-bay in combination with the isolation of the area, this will ensure that no external unpolluted water can enter the area and polluted water is treated before discarding out of the designated area.

Components

of a Waste Water Separation Facility
Sediment Traps

Ecotech Africa constructs and designs sediment control systems to suite specific requirements. The development of a comprehensive sediment control plan is a vital element of an effective water management system. If left unattended, the deposition of silt in areas where adequate provision has not been made could result in a considerable cost to both the client and the environment. Sediment traps and basins provide a cost effective means to reduce the amount of suspended solids in surface runoff. Design criteria along with the level and regularity of maintenance required for sediment control measures are the key issues to their success. Sediment control is an important part of an effective waste water separation system. Dirty runoff from client workings (Workshops, wash-bays, plant & maintenance areas) contains residue that can cause silting up of drains, storm water systems and pollution control dams.

Storm Water Effluent Management

Proven structural storm water runoff system designed to efficiently and effectively treat storm water by separating debris and trapping pollutants before they enter the waterways. All Eco Storm Water Systems, can be fabricated into multiple sizing combinations to fit a variety of applications and custom installations.

An all-inclusive Eco Storm Water Systems treatment train guarantees economy of scale, precise multiple sizing combinations, greater installation flexibility, and superior pollutant removal efficiencies. Eco Storm Water System products consist of two standard pre-cast manholes and the Eco Storm Water System unit. The two manholes allow the removal and storage of pollutants, while Eco Storm Water System directs the flow of water to provide the most efficient treatment possible.

Eco Storm Water Systems are customized to fit your specific project requirements and the diameter and depth of both the primary and storage manholes may be tailored to suit any specific site conditions necessary.

One of the advantages of the Eco Storm Water System is that its design offers unobstructed access for pollutant inspection and removal. By opening either manhole cover, trapped pollutants can easily be seen from the surface, making confined space entry unnecessary. Inspection can be performed though visual observation and by measuring sediment levels.

Normally when the accumulated sediments in either structure reach a height of two feet from the manhole floor, maintenance should be performed on the system. The maintenance cycle typically falls into an annual pattern given normal loadings and sizing. Inspection of the system is recommended quarterly for the first year or more to determine the appropriate cycle based on site characteristics.

Gravity Effluent Separation

Design Feature The design is based upon the API (American Petroleum Industry) research over the past 35 years. It was found that with the Gravity Effluent Separation even without the use of any external separators and or skimmers the lowest count of hydrocarbon parts per million (ppm) will be achieved in the effluent discharged into the environment.

The Gravity Effluent Separation System is easily manageable, cost effective and sustainable. It will also assist the client with compliance to environmental standards and ISO 14001 regulations. Effluent discharged will be within the prescribed 2.5 parts per million and will comply with legislation.
