The present invention relates to a fresh water generation method including: feeding raw water or pretreated water thereof as feed water into a semipermeable membrane module in a pressurized state using a booster pump, thereby separating the feed water into a concentrate and a permeate having a low concentration, in which a scale inhibitor having a reducing function is dosed intermittently or continuously upstream from the semipermeable membrane module, thereby inhibiting scale generation and maintaining an oxidation-reduction potential of at least either the feed water or the concentrate to a threshold value or lower.

An automated descaling system can be integrated into a tankless water heater or can be a separate system that is connected to a tankless water heater. The automatic descaling system comprises a cleaning media chamber and a valve with a motor. The descaling system can be set on an automatic cleaning schedule.

A produced water evaporation system for spray evaporating water comprising a geothermal heat retainment system and an evaporation system is disclosed. The geothermal heat retainment system comprises a first feed inlet, an optional solar collection system or a heat exchanger, and a first discharge outlet. The evaporation system comprises a second feed inlet, a pump, a drip manifold comprising a drip orifice or a manifold comprising a nozzle, a container, wherein a first portion of a ceiling of the container is constituted by a demister element such that the first portion of the ceiling is entirely configured as an outlet for evaporated water and wherein a second portion of the ceiling is adjacent to an upper edge of a wall of the container, a second discharge outlet, and an air system comprising an air blower and an optional air preheater, wherein the air system is disposed through the wall of the container and wherein the air system discharges air flow counter to the produced water and/or water droplets from the drip orifice. A method of using the produced water evaporation system is also disclosed.

The present disclosure relates to a dishmachine that includes one or more features directed to water, energy or material savings. The disclosed dishmachines are still capable of meeting the soil demands of the articles to be cleaned.

A phosphorus-based calcification inhibitor (“inhibitor”) configured to prevent calcification of anaerobic granular sludge.

A liquid dosing system is disclosed and can include an inlet conduit and an outlet conduit. The inlet and outlet conduits can each be configured to fluidly communicate a heat exchanger of a water heater. The liquid dosing system can include one or more connector conduits configured to fluidly connect the inlet conduit and the outlet conduit to define a fluid circuit by at least the inlet conduit, the heat exchanger, the outlet conduit, and the one or more connector conduits. The liquid dosing system can include a pump configured to pump water through the fluid circuit, a reservoir configured to store an additive, and a dosing device configured to dispense the additive into the fluid circuit.

A cooling tower system is disclosed. The cooling system includes a cooling tower; at least two make-up water inlet streams configured to supply water to the cooling tower; a blowdown stream configured to remove water from the cooling tower; at least one sensor monitoring water in each of the make-up water inlet streams; and a controller operably connected to the at least one sensor.
