aluminium sulphate

The treatment plant, where the aluminium sulphate was routinely used to clear the water by removing organic matter, serves 7,000 homes and 20,000 people.

Mixed with water, aluminium sulphate becomes increasingly acid.

Most of the aluminium contamination is due to aluminium sulphate added to water to remove cloudiness.

The low-level, continuous exposure arising from aluminium sulphate in water purification is very worrying.

Foam extinguishers use sodium bicarbonate and aluminium sulphate solution.

There is no running water in Kigali, because of a shortage of aluminium sulphate which helps cut down impurities.

Then on 22 July someone rang Roberts anonymously and told him that a lorry-load of aluminium sulphate had been tipped into the water supply.

In 1988, many people were poisoned in Camelford, when a worker put 20 tonnes of aluminium sulphate in the wrong tank.

The aluminium sulphate was added to the 'contact tank', a bad place because it was the last stage in the treatment process before the water left for the town.

Persistent moisture will weaken aluminium sulphate flame-retardants in cellulose (which are sometimes used in the USA).

Metaldehyde or methiocarb pellets can harm pets or wildlife; organic gardeners should poison with selective aluminium sulphate preparations.

Douglas Cross, a consultant biologist based in Camelford, tested the water and found that it contained "not only aluminium sulphate but other noxious substances, too.

Iron sulphates or aluminium sulphate as well as elemental sulfur (S) reduce pH through the formation of sulfuric acid.

Being unfamiliar with the location, he had been given a key by another driver and told simply that "once inside the gate, the aluminium sulphate tank is on the left".

Eventually they learnt from Dr Grainger that there was some contamination with alum (aluminium sulphate) but that this was 'not particularly dangerous'.

It covers around eighty topics, from building a soapbox racer and tying knots, to learning about famous battles and how to make potassium aluminium sulphate crystals.

When a technician put a decimal point in the wrong place and tipped a hundred times too much concentrated aluminium sulphate into the Tipley Valley supply, five thousand people were made ill.

In June 1989 aluminium sulphate also entered a water supply intended for tens of thousands of people at Fossany Bane Works near Newry in Northern Ireland.

A contractor's relief driver pours 20 tonnes of aluminium sulphate into the wrong tank at a water treatment plant near Camelford in Cornwall, causing extensive pollution to the local water supply.

He poured the load of 20 tonnes of aluminium sulphate, used to remove solid particles from cloudy water, into the tank, which actually held treated water prior to distribution to the consumers in Camelford.

Supplies to 20,000 people were poisoned in Cornwall when a relief delivery driver accidentally pumped 20 tonnes of aluminium sulphate into the wrong tank at the Lowermoor treatment plant near Camelford on 6 July 1988.

After being washed in distilled water, the slides were counterstained with 0.1% nuclear fast red in 5% aluminium sulphate for five minutes, dehydrated, and mounted using a synthetic mounting medium (Vitro-Club, Langenbrink, Emmendingen, Germany).

In July 1988, the water supply to the town and the surrounding area was contaminated when 20 tons of aluminium sulphate was poured into the wrong tank at the nearby Lowermoor Water Treatment Works on Bodmin Moor.

Aluminium poisoning became famous in Britain when on Wednesday 6 July 1988 a 20-tonne lorry-load of aluminium sulphate was poured into the wrong tank at Lowermoor treatment works and polluted the water supply of Camelford in Cornwall.
