Cuando el saneamiento público se vuelve sostenibleEcological cleaning of sewage
When the public sanitation becomes sustainable
Drafting Interempresas31/08/2009
Cleaning of sewers and urban pipes still represents a technological challenge in the water sector. Sustainable sanitation through the use of technology to help lower consumption of drinking water. Hidrocar works with sewage from the culvert itself, without using water.
Hidrocar special vehicle for green cleaning of sewers.
Environmental approaches open step in cleaning of sewers, 'not visible' infrastructure but by no means, of lesser importance when we talk about quality of urban life. The Hidrocar company has a fleet of heavy-duty trucks and light vehicles for ecological cleanliness of the sewers. Part of the company, ecological sanitation moved their trucks mark Müller, a European firm pioneer in water recycling technology.
Use of waste water instead of drinking
Aware of the need of saving water in urban areas, Hidrocar incorporates the concept of water recycling its fleet. Through eight stages of filtering, the vehicle works with waste water from own sewer without using drinking water. When extracted to pressure the record that obstructs the pipe, the truck separates it from the water, which then recycles. This procedure away impurities. In short, be indefinitely, reuses the same water with the advantage of not having to fill the tank. Thus avoiding wasting litres of the liquid, vital to the well-being of the citizen.
In economic terms, it is a beneficial procedure due to twice the power of high pressure pumps (476 litres minute to 150 bar) and the pump's suction to 2100 m3 per hour, compared to a conventional truck. In general, this company is dedicated to clean up spaces that require special means, whether they are cleaning equipment with water pressure or others. For example, farms and graves of purines, wells, ponds, pools, treatment plants, facades, stores, streets and drainages.
Hidrocar has a van equipped to carry out a full study of the piping and pipes of a certain area, through a closed-circuit TV camera. From the vehicle, turns the camera with which the data reflected in the report are calculated: pending of the pipes, digital photos in case of failure, drawings of the various sections of the pipes, and so on. Thus detected where and how it can act directly on this problem.

Sanitation and rehabilitation of pipelines
Occasionally, the flaws in a pipe are not so large as to renew pieces whole. The existence of cracks, fissures, holes, damage by corrosion or slightly damaged joints, among others are settled through the Parlining system. In particular, this procedure is used for partial damage lasting repair on pipelines, on the basis of the binomial fiberglass and resin. A robot, controlled by a camera, which is installed alongside the damaged Canal is used for the repair of joints and cracks. Through pressure, this robot looks at the walls of the channel with a mixture of resins and fiberglass. The wall of the tube, the resin and glass fiber form one body. With this system, are restored pipes with diameters DN 150 to 800, without making any kind of excavation. During the work of improvement, the channels can keep up and running.
Hidrocar is also dedicated to the suction of sludge, liquid, septic tanks and cesspools, among others.
Location of blockages in pipes and sewerage
Sometimes, some pipes and sewers not be can unblock with cleaning equipment with high pressure water. Generated blocks that require digging the soil, in order to carry out repairs. To this end, is used a computer to detect, in a precise way, the focus of the problem. In other words, where is the congestion. During the process, a probe is inserted into the duct through a nozzle suitable for this use, or also via manual. The probe stops at the place of the jam or break and emits signals, to a certain frequency, that the receiver picks up from the outside. In this way, the point through which passes the vertical line to the probe is located.
Japanese painting graffitiThe HLG system, from the hand of Hidrocar, has four basic properties: prevents and avoids the appearance of graffiti, prevents the adhesion of stickers, facilitates the cleaning and disinfection and an inorganic layer that protects the surface of weathering. In short, it is the first green paint of inorganic nature and Japanese patent does not pollute.
