New Low Pressure Automatic Water Filter Reduces Pump Energy Requirement

Forsta introduces a new line of low pressure automatic industrial water filters. Low Pressure self-cleaning water filters range from 2"-30" with flow rates range from 15-20,000gpm in a single filter housing . Until now self-cleaning water filters required over 35psi for backwashing, but the new Low Pressure Series design provides an ideal energy saving solution in applications with line pressure as low as 15 psi. Equipped with Green-Clean technology, the Low Pressure Series point-of-suction backwash takes less than 16 seconds and uses less than 1% of the total flow per backwash without interrupting the main flow. Filters are available in stainless steel, carbon steel with epoxy coating or duplex stainless. The Low Pressure Series is ideal for process water, cooling water, wastewater, spray nozzle protection, and other industrial applications.

Forsta Filters for Greenhouse

Every greenhouse irrigation system should incorporate proper filtration of the water supply to protect small drip or sprinkler orifices from clogging. Any clogging (which may occur if unfiltered water is utilized) will cause disastrous results in uniformity. In the case of drip irrigation, some plant material will not be irrigated at all if the lines are closed by debris.

Pressure regulation is typically used in most greenhouse irrigation systems to ensure that emission devices are operating uniformly and that they are within the specifications of the manufacturer's design. It is typical to have the filter and pressure regulator located near the greenhouse water source. From that point, the irrigation pipeline is usually divided into a manifold, with valves controlling different areas of the greenhouse, or handling different types of irrigation systems within the same greenhouse. Depending upon the level of automation that the greenhouse operator desires, the valves can be manually activated or activated by an electronic, programmable controller. The filter, pressure regulators, manifold and valves make up the "control head" of the irrigation system. Regardless of the type of irrigation pipeline and emission devices which are used, every greenhouse irrigation system should have a "control head" at its water source within the greenhouse.
