A NEW STYLE OF SAND FILTRATION.
Among the ordinances referred to Director Thompson by the water committee of Philadelphia councils, is one for an improved system of sand filtration, by which it is proposed to place the filters on land now owned by the city adjoining the several reservoir_____, thus obviating the necessity for extensive land purchases, and applying all appropriations for the construction of the filters. It also proposes to construct plants to filter the entire water supply for $3,200,000. It is claimed that the above plan will prove itself to be efficacious, practical, durable, and inexpensive in operation. This filtration plan, as submitted to Director Thompson,does away with the natural film that forms on the top of the sand where the filtration proper takes place and catches the bacteria, and substituting for it at artificial film of mineral asbestos, which is not soluble in w iter and will not ferment. It is mixed in water and settles to the surface of the sand, making a thin felt covering the entire surface, so close in texture that, it is claimed, no bacteria can pass through it. When the deposit filtrated from thi water becomes too thick, the layer can be pulled off and rolled from the sand, leaving the latter apparently clean. Another deposit of felt can be made, and the filter be put in service again, it is stated, before it would be possible to scrape the bed of an ordinary sand filter.
The constr ction proposed is to build the filters three tiers high, where space is valuable, of steel and concrete Such filters operate four times as fast as the usual si’: feet deep beds, and they would, therefore. require only One-twelfth the space. As all filters require to be covered in a climate like ours, to prevent damage by freezing, this method is advantageous. as one roof covers three beds.
Rcftrring to available space.lt is proposed to filter the wuer supplied bv the East I’.irk reservoir on the space between the reservoir and Thirty-third street, ami the water of the Roxbrough reservoir and between the reservoir and Ann street. The Queen Lane supply would be filtered on the irregular plot at the coiner of Abbottaford avenue and Thirty-first street. Plans for the work accompany the ordinance.
While Milton Garvin and his wife were in the barn of their home across the Kentucky line, in Clay county, Tenn., their house took fire and their four children, ranging in age from one year to seven, were burned to death. The screams of the little ones brought the parents on the scene, and in their frantic efforts at saving their infants both had a narrow escape from death. The four children bnrned to a crisp before the parents’ eyes.
At Brownsville. Tenn., a fire which started in Johnson’s cotton gin spread to the Methodist church, a residence, and a barn adjoining, all of which were gutted. In the Methodist church, which cost $30,000, a $2,000 organ was burned. In the cotton gin were forty bales of cotton and a large quantity of cotton seed. Total loss, $8o,ooo, with no insurance si round.
