A liquid treatment unit removes particulate matter and colloids from a liquid, as found in waste water on mines, on construction sites and on heavy industry sites. The liquid treatment unit includes an electrocoagulation unit and a cyclonic separator unit. The liquid to be treated is first subject to electrocoagulation and then fed into the cyclonic separator unit. The cyclonic separator unit guides the electrocoagulated liquid in a circular path downwardly from an outer perimeter to move underneath a skirt and then upwardly and inwardly towards a central outlet located at the top of the cyclonic separator. Floating particles are skimmed from the surface outside of the skirt. In moving to the outlet, the liquid passes through a plurality of nested frusto-conical guide members. An ultrasonic transducer is used to collapse bubbles formed by electrocoagulation, and to clean the electrocoagulation electrodes.

A submersible substance separator system having an outer chamber, a top cover plate, an upper cup, a disc stack separator; a middle cup, a submersible actuator, a lower cup, and an interior chamber within the outer chamber; in which one section of the disc stack separator is configured to lead, in response to centrifugal forces, a first separated substance into the upper cup and subsequently into the outer chamber until it reaches a chamber outlet corresponding to the outer chamber; and wherein another section of the disc stack separator is configured to release, in response to centrifugal forces, a second separated substance into the interior chamber until it reaches a chamber outlet corresponding to the interior chamber.

Embodiments of treating fluid comprising hydrocarbons, water, and polymer being produced from a hydrocarbon-bearing formation are provided. One embodiment comprises adding a concentration of a viscosity reducer to the fluid to degrade the polymer present in the fluid and adding a concentration of a neutralizer to the fluid to neutralize the viscosity reducer in the fluid. The viscosity reducer is buffered at a pH of 7 or less (e.g., at a pH of from 2 to 7, such as at a pH of from 3.5 to 7, or at a pH of from 5 to 7). The addition of the concentration of the viscosity reducer is in a sufficient quantity to allow for complete chemical degradation of the polymer prior to the addition of the concentration of the neutralizer in the fluid such that excess viscosity reducer is present in the fluid. The addition of the concentration of the neutralizer is sufficiently upstream of any surface fluid processing equipment to allow for complete neutralization of the excess viscosity reducer such that excess neutralizer is present in the fluid prior to the fluid reaching any of the surface fluid processing equipment.

The present system is for simultaneous recovery of purified water and dissolved solids from impure high TDS water (1) which is achieved in a single step and eliminates the use of external thermal energy for making the system significantly efficient. It eliminates the use of boiler, cooling tower that reduces the overall capital cost and continuous requirement of external thermal energy for making system efficient. The simultaneous recovery of the purified water and solids from high TDS input effluent reduce the energy intensity of the system. Said system provides a vacuum system as heat pump which enables the system to be self-sufficient in thermal energy requirements for evaporation process and reduces GHG emissions significantly.

A thin film, direct convection, evaporative process and apparatus for treating waste water on-site at a production area or waste water processing area relies on direct exposure of waste water to an open flame in an evaporation chamber, despite the waste water containing volatile substances, resulting in up to 99% reduction of total flow rate of waste water, and creating steam capable of being introduced safely to the environment.

The invention relates to desalination systems for separating water from solids and/or undesirable solutes such as salt (sodium chloride). In particular, the invention relates to a desalination system for producing potable water. In a preferred embodiment, the invention produces potable water from salt water such as naturally occurring salt water. The desalination system uses droplets of salt water suspended in an air stream to evaporate into water vapor and particles of salt to be separated using a commercially available cyclone separator. The water vapor is thereafter condensed into potable water.

An oil and grit separator system having twin vortex which uses gravity providing a twin vortex effect to remove sediment and oil from contaminated water. The system is designed to control storm water runoff and reduce the annual suspended solids loading of the granulometric particles. The conception and configuration of the system has a double action vortex. It ensures an optimal treatment level in either light or heavy rain and avoids re-suspension of particles. It also removes, separates and stores floating oil without any possible re-suspension of the matter.
