LIQUITECH srl

Manure treatment system and biogas production plants

HISTORY :

Company Liquitech srl has been established in 2001.

It is a brand new company indeed, even though it has all the experience gained by Brevetti Francesco Cremonesi S.p.A. in manure treatment market, coming from a decades of activity in such a field.

The way how to solve the manure problem in the proper method, raised up to the farmers attention, as soon as the modern livestock technique was born in the early 60’s.

During this decade Brevetti Francesco Cremonesi S.p.A. started to manufacture the first bels and scrapes to remove the manure from the barns.

In 1984, cooperation with Eisele, German company production leader in pumps and mixers for manure, has been taken place.

In 1986, Maurizio Marzona, now technical responsible for Liquitech, starts working in Liquitech.

In 1989 the first concrete storage tanks have been manufactured, with the put-in-place technique, using special, self standing moulds built by Brevetti Francesco Cremonesi S.p.A.

At the same time an agreement with English company Permastore, worldwide leader in glass fused to steel tanks and silos, has been signed.

In 1994 the first fibreglass manure tank has been imported by Brevetti Francesco Cremonesi S.p.A., form Eisele company, in order to fulfil the requests of the customers.

In 1997 the first umbilical system, to spread the manure on the fields, has been sold, using pumps from German company Wangen.

One year later Brevetti Francesco Cremonesi S.p.A. starts working on Biogas systems, and projects

are developed by means a cooperation with specialized technicians and engineers.

The experience and acknowledgment acquired by Brevetti Francesco Cremonesi S.p.A. become the strong bases on which Liquitech was founded in 2001.

Nowadays Liquitech srl has hundreds of installations functioning in Italy and Europe, and the first biogas installations now are working.

INSTALLATIONS:

· Complete manure treatment systems : circulation under the grates, manual or automatic system, controlled by PLC and pneumatic actuators; charge of storage tank; mixture of storage tank, PVC discharge pipelines equipped with automatic and manual operated valves; oxygenation plants; separators for liquid/solid components; storage tanks for manure and other liquid.

· Umbilical systems for manure spreading. Capacity up to 180 cubic meter/h, by means of Wangen pumps, GL series. SNAP-TITE special hoses, diameters from 2” to 6”, with 48 bar loading break. Optional injectors for manure spreading.

· Complete systems for biogas production from zootechnical manure. We are developing Eisele technologies in this field, that is a very simple and efficient system, controlled from PLC programs. This plants allow to obtain electrical and thermal energy at zero cost. The manure going out from the plant is much more better than when it enters the system.
