Treatment fluid disposal in chemical cleaning processess for drinking water facilities

A process for the disposal of treatment fluid runoff from drinking water facilities cleaning procedures is disclosed. Due to accumulating sediments, mineral deposits and biological contamination, drinking water tanks and facilities must be cleaned on a regular basis to guarantee water quality and reduce the amount of chlorination required.

The invention provides a runoff disposal process including the principle steps of collecting the runoff in a holding facility, analysing the pH of the runoff, neutralizing the pH of the runoff with a pH neutralizing agent, and filtering the runoff to remove suspended particulates. Additional steps may include analyzing the chlorine residual in the runoff, and de-chlorinating the runoff with a de-chlorinating agent.

Water treatment apparatus and system

A portable flocculation, filtration and chlorination system

A portable flocculation, filtration and chlorinisation system intended for the purification of non-saline water drawn from a variety of sources e.g. surface water, river, borehole etc. to drinking water conditions. This is achieved by the already flocculated water passing through two primary filters. Chlorinisation takes place by the use of a water-driven dosing pump capable of dosing at the rate of 2ppm and upwards as required. The water then passes through its final stage of purification where use is made of an advanced filter media. This media is selfsterilising because of its permanent high surface catalytic properties and negative zeta potential. The negative zeta potential allows the filter media to adsorb positive charged metal ions from the water such as iron and manganese. The water having passed through this filter is of micron or sub micron standard. The treated water is then stored in an incorporated holding tank ready for later use as and when required. This stored water is ...

Methods for the treatment of ballast water

A process has been developed to selectively dissociate target molecules into component products compositionally distinct from the target molecule, wherein the bonds of the target molecule do not reform because the components are no longer reactive with each other. Dissociation is affected by treating the target molecule with light at a frequency and intensity, alone or in combination with a catalyst in an amount effective to selectively break bonds within the target molecule. Dissociation does not result in re-association into the target molecule by the reverse process, and does not produce component products which have a change in oxidation number or state incorporated oxygen or other additives because the process does not proceed via a typical reduction-oxidation mechanism. This process can be used for the remediation of water, particularly ballast water.

Electrolytic Treatment Method of Olive Mill Waste Water

The invention refers to the electrolytic treatment of olive mill waste water with recovery of the residual oil, removal and valorization of the solids and subsequently to the wet oxidation of oil free waste through electrolytic produced oxidants, the inactivation of the oxidants, the passing of the treated wastewater through activated carbon and their final treatment by the process of reverse osmosis and the recovery of the Sodium Chloride that is recycled, returning in the process of the electrolytic treatment of the oil free olive mill waste water. 1. Electrolytic treatment method of Olive Mill Waste Water , during which , olive mill waste water pass through grids of specific gaps and then is subjected to flotation with Nitrogen (N) , which through an appropriate porous ceramic diffusers device enters the waste water stream with a specific diameter range bubbles and where the residual oil floats and it is removed by a surface scraper , then , the oil free olive mill waste water is mixed with brine deriving from the discharge of the reverse osmosis , or has been prepared from water and NaCl , and acquires a specific salinity , then , the oil free olive mill waste water; having acquired a specific salinity , passes through a special type flotation clarification unit , where chemicals are injected at different stages of the oil free—and having salinity—olive mill waste water treatment process , while the pH and the quantity of the injected chemicals are controlled by the PLC , at this point , the flotation of solids included in the aforementioned waste water is achieved by injecting air with specific diameter range bubbles , through a special nano-bubble production pump and a suitable porous ceramic diffusers device and the floating solids removal is being done by a double scrapper device , afterwards , the oil free—and having salinity—olive mill waste water pass through self-cleaning filtering units of specific gaps and are then forwarded for electrolysis by non- ...
